CONNECTING STRUCTURE BETWEEN CAST-IN-PLACE PILES, CONSTRUCTING METHOD THEREFOR AND INTER-PILE CUTTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a joining structure for providing high water stop property and prescribed strength between adjacent cast-in-place piles. SOLUTION: An inter-pile cutting device 10 is elevatably suspended within a pile groove 3 of a succeeding cast-in-place pile 2 toward a preceding cast-in- place pile 1 prepared at a prescribed plane interval in advance. A wall-shaped groove 5 is formed between the preceding cast-in-place pile 1 and the succeeding cast-in-place pile 2 by high pressure jet flow injected from a high pressure jet pipe 40 equipped on the inter-pile cutting device 10. By forming a wing- shaped wall 4 by integrally placing concrete on the wall-shaped groove 5 and the succeeding cast-in-place pile 2, the succeeding cast-in-place pile 2 and the preceding cast-in-place pile l are integrally connected.
